Development Mezzanine Card

The Development Mezzanine Card (DMC) is an optional plug-on card mounted on the back of the PmPPC7448 board to expedite product development. This chapter describes the physical layout of the DMC, the setup process, and how to check for proper operation once the board has been installed. The DMC facilitates hardware and software development by providing:

•Four LEDs for software development (connected to the MV64460 MPP pins)

•An EIA-232 debug serial port (mini-USB connector) with cable to DB-9 connectors

•JTAG/COP header for software development

•JTAG header for CPLD programming

•A 32-pin, PLCC 8-bit ROM socket for software development

•Four software-readable jumpers for development use

DMC CIRCUIT BOARD

The DMC is a custom four-layer circuit board. It has the following physical dimensions.
